tools/firewire: nosy-dump: guard close(fd) when reading from input file

The file descriptor fd is initialized to -1 and only opened via open()
when the --input option is not used. However, close(fd) is called
unconditionally at the end of main(), which results in close(-1) and
a spurious EBADF error when nosy-dump reads from an input file.

Guard the close() call with "if (fd >= 0)" to match the existing
conditional cleanup pattern used for the output file handle.
